PERIOD COVERED:  0000Z (UTC) 11/03/97 - 0000Z (UTC) 11/04/97

Daily Status Report as of 308/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental
Darks PT1/3)

       The WF/PC-2 was used to make supplemental dark calibration images.
This set of calibrations is intended to obtain three dark frames every day
to provide data for monitoring and characterizing the evolution of hot
pixels.  The observations were executed as scheduled, and no anomalies were
noted.

   1.2 Completed Two Sets of STIS/CCD 7635 (STIS CCD Hot Pixel Annealing)

       The Space Telescope Imaging Spectrograph (CCD) was used to test the
hot pixel annealing procedure.  The effectiveness of the CCD hot pixel
annealing process is assessed by measuring the dark current behavior before
and after annealing and by searching for any window contamination effects.
The observations were completed as planned, and no problems were reported.

   1.3 Completed Four Sets of WF/PC-2 7620 (WF/PC-2 Cycle 7 Standard Darks)

       The WF/PC-2 was used to make a series of Cycle 7 standard dark
calibration images.  This calibration program obtains dark frames every
week in order to provide data for the ongoing calibration of the CCD dark
current rate, and to monitor and characterize the evolution of hot pixels.
The observations were executed as scheduled, and no anomalies were noted.

   1.4 Completed Two Sets of NIC/1/2 7454 (The Stellar Content of Powerful
Radio Galaxies -- A NICMOS Survey of 0.8 < z < 1.8 3CR Sources)

       The Near Infrared Camera (Cameras One and Two) was used to make
survey observations of the powerful radio galaxies 3C184 and 3C368.  The
study of distant radio galaxies is complicated by their powerful active
nucleus, whose emission dominates at rest-frame ultraviolet wavelengths,
producing the observed peculiar, elongated morphologies; the underlying
stellar component is lost in the glare.  The observations were completed as
planned, and no anomalies were reported.

   1.5 Completed STIS/CCD 7802 (Daily Darks to Update Acquisition Bad Pixel
Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations to obtain daily darks to update the acquisition
bad pixel table.  These daily darks are intended to identify hot pixels for
update to the acquisition on-board FSW hot pixel table.  Daily hot pixel
lists can also be used for science data analysis.  The observations were
executed as scheduled, and no anomalies were noted.

   1.6 Completed Four Sets of STIS/CCD 7783 (STIS Parallel Science)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations taken in parallel with the prime science.  The observations
were completed, and no problems were reported.

   1.7 Completed NIC/1/2/3 7447 (The Cosmological Evolution of Quasar Host
Galaxies)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of galaxy 1148+56W1 as part of a survey to study the
cosmological evolution of galaxies which host quasars.  Other point spread
function observations were taken to test the calibration of the cameras.
The observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed STIS/CC 7782 (STIS Non-Scripted Parallel Archive Proposal
- Half Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one-half orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.9 Completed NIC/1/2 7321 (Spatially Resolved Multispectral
Investigation of Titan's Troposphere and Stratosphere)

       The Near Infrared Camera (Cameras One and Two) was used to make
observations of Saturn's moon Titan in order to study its atmosphere.
Saturn's moon Titan has a thick, hazy atmosphere obscuring a surface that
has only recently been observed in the near-infrared. Despite observations
of surface albedo features, the nature of the surface remains hidden due to
our imprecise knowledge of the atmosphere.  The observations were executed
as scheduled, and no anomalies were noted.

   1.10 Completed WF/PC-2/NIC/1/2/3 7414 (Imaging of a New Beta Pic-like
Circumstellar Dust Disk)

       The WF/PC-2 and the Near Infrared Camera (Cameras One, Two, and
Three) were used to obtain high-resolution mapping of the recently
discovered circumstellar disk around the B5V binary BD+31D643 (a.k.a.,
HD281159).  The observations completed as scheduled, with no reported
anomalies.

   1.11 Completed Four Sets of WF/PC-2 7786 (Pure Parallel Archive Survey -
Continuation)

       The WF/PC-2 was used to make observations as part of an archival
survey program in which the images were taken in parallel with the prime
science observations.  These WF/PC-2 parallel observations were obtained in
the ultraviolet in a search for interesting objects.  The observations were
completed as planned, and no problems were reported.

   1.12 Completed S/C 5582 (FOC/48 Monthly Activation (Camera Section
Only): Cycle 4)

        This proposal was executed as scheduled, and no anomalies were noted.

   1.13 Completed WF/PC-2 6467 (Precise Astrometry in the Core of the
Globular Cluster 47 Tuc: A Complete Census of High-Velocity Stars)

       The WF/PC-2 was used to make images of the cluster NGC-104 (a.k.a.,
47 Tuc) in order to make precise astrometric observations of the clusters
core.  Hard binaries are known to exist in cluster cores, e.g., in the form
of millisecond pulsars.  The observations were completed as planned, and no
anomalies were reported.

   1.14 Completed WF/PC-2 7386 (A Snapshot Survey of Nova Shells)

       The WF/PC-2 was used to make observational images of the super nova
shell V4332-SGR in order to detect and measure its expanding gaseous shell.
These observations will trace the distribution of hot and cool gas in the
nova shells, and show their degree of inhomogeneity on both large and small
scales.  The observations were completed as scheduled, and no problems were
noted.

                                        Successful : 8

       As described in HSTAR 6231, one acquisition defaulted to fine lock
on one FGS only at 308/0811Z.  This may have affected one STIS and two
NICMOS proposals which will be identified in tomorrow's report.

                          Scheduled Reacquisitions : 7
                                        Successful : 7
